Overview

None of the above solutions work with a multi-level hash They only work on the first level: :level1=>{“level2”=>“baz”} The following two variations solve the problem in the same way transform hash keys to symbols multi_hash = { ‘foo’ => ‘bar’, ‘level1’ => { ‘level2’ => ‘baz’ } } multi_hash = multi_hash.deep_string_keys
